An information handling system may include a processor, a device communicatively coupled to a processor via a communications link including a cable assembly, and a management controller communicatively coupled to the processor and communicatively coupled to the device and the cable assembly via a sideband interface, and configured to: retrieve, via the sideband interface, self-describing signal integrity critical parameters from non-transitory computer-readable media integral to the device; retrieve, via the sideband interface, self-describing signal integrity critical parameters from non-transitory computer-readable media integral to the cable assembly; combine the self-describing signal integrity critical parameters from non-transitory computer-readable media integral to the device and the self-describing signal integrity critical parameters from non-transitory computer-readable media integral to the cable assembly into aggregate signal integrity critical parameters; and perform an action relevant to the communications link based on the aggregate signal integrity critical parameters.
Legal claims defining the scope of protection, as filed with the USPTO.
3. The information handling system of claim 2, wherein the information handling resources making up the communications link other than the cable assembly and the device include at least one of a motherboard comprising the processor or a circuit interfaced between the processor and the device.
4. The information handling system of claim 1, wherein performing the action comprises communicating the aggregate signal integrity critical parameters to a basic input/output system (BIOS) of the information handling system.
6. The information handling system of claim 5, wherein performing the second action comprises one or more of: ensuring a valid or validated configuration for the communications link, tuning the communications link, relaying preset hints to components within the communications link, limiting a speed of the communications link, and performing authentic cable attestation of the cable assembly.
7. The information handling system of claim 1, wherein performing the action comprises one or more of: ensuring a valid or validated configuration for the communications link, tuning the communications link, relaying preset hints to components within the communications link, limiting a speed of the communications link, and performing authentic cable attestation of the cable assembly.
10. The method of claim 9, wherein the information handling resources making up the communications link other than the cable assembly and the device include at least one of a motherboard comprising the processor or a circuit interfaced between the processor and the device.
11. The method of claim 8, wherein performing the action comprises communicating the aggregate signal integrity critical parameters to a basic input/output system (BIOS) of the information handling system.
13. The method of claim 12, wherein performing the second action comprises one or more of: ensuring a valid or validated configuration for the communications link, tuning the communications link, relaying preset hints to components within the communications link, limiting a speed of the communications link, and performing authentic cable attestation of the cable assembly.
14. The method of claim 8, wherein performing the action comprises one or more of: ensuring a valid or validated configuration for the communications link, tuning the communications link, relaying preset hints to components within the communications link, limiting a speed of the communications link, and performing authentic cable attestation of the cable assembly.
17. The article of claim 16, wherein the information handling resources making up the communications link other than the cable assembly and the device include at least one of a motherboard comprising the processor or a circuit interfaced between the processor and the device.
18. The article of claim 15, wherein performing the action comprises communicating the aggregate signal integrity critical parameters to a basic input/output system (BIOS) of the information handling system.
20. The article of claim 19, wherein performing the second action comprises one or more of: ensuring a valid or validated configuration for the communications link, tuning the communications link, relaying preset hints to components within the communications link, limiting a speed of the communications link, and performing authentic cable attestation of the cable assembly.
21. The article of claim 15, wherein performing the action comprises one or more of: ensuring a valid or validated configuration for the communications link, tuning the communications link, relaying preset hints to components within the communications link, limiting a speed of the communications link, and performing authentic cable attestation of the cable assembly.
